This research develops and tests a model for the prediction of tender offer outcomes. Variables that increase the supply of "obtainable shares" (such as increased bid premiums or the payment of solicitation fees) are shown to increase the probability of success. Increased ownership of target firm shares by the bidder also increases the probability of success. Variables that impede the tendering of shares (such as target management opposition or a competing bid) decrease the probability of success. Tests of the model utilizing both linear and logistic analysis support the theoretical constructs and help resolve the paradoxical findings of previous research.
